JQuery :: Calling Methods And Having Them Execute In A Pre-Designated Order?
May 3, 2009
QUESTION: How does one control the order in which jQuery methods are called and executed when loading a page? BACKGROUND: This question has been simplified from my previous question on load order. As this appears to be a complex issue -- otherwise, it would probably have been readily addressed -- I could likely be satisfied by a link or two that points to a well-written document on this topic.

I've previously written an image carousel with lightbox and to be honest forgot about it for quite a long time. I've just been tasked with making a few modifications (I wrote this code about 6 months ago)
Now, the problem I have is that I now need to call the internal method from the ligthbox plugin.
I've tried setting a reference to this like this but it just won't play ball. I can see that the ajax feed gets called but unfortunately I can't then access it.

The javascript fails to call an embeded applet's function. In the javascript
console, it shows "Error XXXX is not a function". Following are some parts of my code.
if(parent.document.cpmApplet){
parent.document.getElementById('cpmApplet').refreshCPMApplet();
}
if(parent.BottomIframe.document.resultApplet){
parent.BottomIframe.document.getElementById('resultApplet').refreshTableApplet ();
}
Here parent.document.cpmApplet and parent.BottomIframe.document.resultApplet are valid since I loaded both the applets with the same name using <APPLET> tag for Netscape/Mozilla and OBJECT tag for Windows.
The issue is with Netscape and Mozilla on Unix platforms only. I would appreciate if anyone could help me to solve this.

But how do I make this button search google and search for whats in searchField1. I would really appreciate the help. Im looking everywhere to learn this but just cant find it.

I have a form button with id="submit". When pressed, ClickGeocode(credentials) is called. This works fine and dandy with: $('submit").click(ClickGeocode) Despite there being no indication that the function takes an argument 'credentials'. So when I want to call the function at some point in my code, I should be able to do something like ClickGeocode(credentials) ... no? However, my issue is that credentials isn't once defined in my code - it is part of Bing Maps function... like so:
function ClickGeocode(credentials)
{
map.getCredentials(MakeGeocodeRequest);
}
So why does it work using .click(), and how can I call the function without user interaction (simply somewhere in my code) even if 'credentials' is not defined?

About when to use setter methods. For example, I have this code
Should this be used like this:
I think a better question is when to use the .each loop? Since, the first line of code I have works fine.

I have been trying to discover why the first() and last() methods are not working in my jQuery 1.2 nor 1.3 tests. After searching for a while, I found the alternative way with filter() and eq(), but I still wonder why none of those methods work.
The API documentation [URL]... states that they are available since 1.2, but they won't work, I always get a "not a function" error. I also found a tracker entry [URL].. discussing the need for them, but nothing is clear from it.

Let's say I have a Javascript object that looks like this:
{
events: {
"comments:added": this.add,
"comments:removed": this.remove,
"comments:fetched": this.addAll
}
}
I'd like to add this method to it, either manually, using $.extends() or _.extends():

HTML5 brings two new methods to the js selector API: querySelector() and querySelectorAll(). These methods can be used to match elements against a group of selectors. I think, a lot of the functionality overlaps with jQuery selectors. My guess is that these new methods will be a few times faster than jQuery selectors because they are natively implemented. My question is, how will jQuery use these additions to the js selector API? Will jQuery selectors just encapsulate these new methods? If so, is this work in progress or..

I'm trying to use delay() before changing the html contents of an object.Eg. myobj.text("Hi There").fadeIn().delay(2000).text("Bye!").fadeOut();The result of this is that it just shows "Bye!" then fades, without any delay. So delay() seems only to work only with effects methods (fade, etc) not with other methods.Is there any way of getting around this and making a pause between any type of method in a queue?

The following used to work with version 1.3.2
var x = $('#ElementID').val();
var x = $("'#" + "ElementID" + "'").val();
var eid = "'#" + "ElementID" + "'"; var x = $(eid).val();
Only the top one works with version 1.4.1
Similarly the following used to work with 1.3.2 but it doesn't work anymore.
var eid = "ElementID"; $("'#" + eid + " option[value='" + x + "']'").attr('selected', 'selected');

Here are the descriptions for the Ajax methods:
load -- Loads HTML from a remote file ...
ajax -- Load a remote page ...
get -- Load a remote page...
getScript -- Load and execute a local javascript file...
post -- Load a remote page...
So, if we want arbitrary HTML we have to use "load", but if we want a whole "page" (where is that defined?) we have to use "ajax", "get" or "post"? The "execute script" function (called getScript for some reason) only works with local "files"? I believe it will work with any URI (local or remote) returning JavaScript (assuming same origin policy of course), and whether it came from a file isn't known to the caller. These functions should describe the type of HTTP request they make, and skip references to "pages" and "files".

I am pretty excited in creating multiple methods within a single plugin. But how do we access a particular set of objects from any given method? Here is what I have so far and all i want to do is access the objects 'location' and 'background' when the DOM is ready...
*jquery plugin*/
(function($){
//call multiple functions inside of one large plugin that do different things!
var methods = {

Does anyone know if there is a significant performance difference between the below two methods of DOM creation in jQuery?
Method 1:
$("<div id='myId' class='one two three' style='width:100px; height:100px; z-index:1;' />").appendTo("body");
Method 2:
$("<div />").attr("id", "myId").addClass("one two three").width(100).height(100).css("z-index", 1).appendTo("body");
I imagine that when using the first method, jQuery does some string processing and eventually ends up doing the same thing as method #2. Is that correct? If so is there a significant performance cost for this? Overall I think the first method is better as far as readability goes but it would be good to also know its effect on performance.

I'm using the class= style of setting up Validation. I have everything working except: 1. the equalTo method for email and repeat email, and 2. the rangelength method of the length of the password. It turns out the documentation example of equalTo in the housing web page demo is incorrect.[URL]... You can put 2 different email addresses in and Validation will not identify the difference and does not create an error message.
I've tried several things, but can't get the class style to validate equalTo or rangelength. The 2 current expressions I'm using are:
class="required email equalTo:'#contactEmailAddress1' "
class="required rangelength[6, 12]"
For the email, required and email format properly validate, but equalTo does not. What should I change?

Could anyone please explain why my validation doesn't work? When I use only predefined validation methods everything seems to be fine, but when I use a custom method it doesn't do anything until I click submit and then cancels the submit with "$.validator.methods[method] is undefined". The debugger does never jump into the "noBefore" method, I got a breakpoint at the first line. I've tried to write the "notBefore" in quotes in the rules but that doesn't seem to help either.Everything seems to be right, though.

I have a set of functions that will transition/fade photos in and out as background images. Easy. But now I would like to run the same functions on a different html page with different photos (each different page represents a different JavaScript array).
I've been reading online on how jQuery methods can be called into functions. So my thought process is to create 2 methods (1 for the original images and the 2nd method for the other images).
So here is my base code which works...
$.landingpage = function() {
/*Enable background image cycles on landing page*/
var images=new Array('/image01.jpg','/image02.jpg');
var nextimage=0;

I have an object on the document element that allows for other components to register with it, i have a custom event something along$(document).bind("register",function(thechild)..So in the child object when they are created i call$(document).trigger("register",this);And indeed i get the DOM object. However i'm looking for the plug in object, i want to be able to call methods on the passed childobject and access it's Config.Does that make sense? How can i write a plug in that is applied to various objects that also registers itself with an 'overseer' object on the document element in such a way that i can allow that overseer object to call methods on any registered child objects?

When I use .load to load a html page into a div, the javascript that is meant to run on the page does not excecute. I've done a search on ways to append the script into the div, and found things like $.ajax and $.getScript, but it couldn't get it to work. I read something about eval()... but that confused me a fair bit.
